1 KBit READ / WRITE
CONTACTLESS IDENTIFICATION DEVICE
Description
The EM4150/EM4350 (previously named P4150/P4350)
is a CMOS integrated circuit intended for use in electronic
Read/Write RF Transponders. The chip contains 1 KBit of
EEPROM which can be configured by the user, allowing a
write inhibited area, a read protected area, and a read
area output continuously at power on. The memory can
be secured by using the 32 bit password for all write and
read protected operations. The password can be updated,
but never read. The fixed code serial number and device
identification are laser programmed making every chip
unique.
The EM4150 will transmit data to the transceiver by
modulating the amplitude of the electromagnetic field, and
receive data and commands in a similar way. Simple
commands will enable write to EEPROM, to update the
password, to read a specific memory area, and to reset
the logic.
The coil of the tuned circuit is the only external component
required, all remaining functions are integrated in the chip.
The only difference between EM4150 and EM4350 is that
EM4150 comes with standard sized pads, whereas
EM4350 comes with oversized (mega) pads, ideal for use
with bumps on die (Fig. 27).
